Should this actually be merged with method above? I don't see this method
actually refreshing anything. Am I missing something?

Yes, changed to use this method to refresh instead of the event listener.

+    this.dispatchEventToListeners(Resources.IndexedDBModel.Events.DatabaseRefreshed, {databaseId: databaseId});

     this._agent.clearObjectStore(databaseId.securityOrigin, databaseId.name, objectStoreName, callback);
   }
